Summary

OpenAM before 16.1.4 and its client SDK fail to sufficiently validate responses on the internal server-to-server SOAP channel, allowing network-positioned attackers to affect integrity and availability. Attackers who intercept unencrypted traffic or control a site server can crash receiving processes, tamper with writable files, and possibly execute code.
